The need for tall buildings are steadily increasing all over the world, in parallel to the need for new living spaces in large cities. Improvements in technological equipment, material science and analysis methods have opened opportunities to construct new life areas by rising along the vertical direction instead of horizontal. Unlike regular buildings, tall buildings are peculiar due to their specific architectural properties and building configurations. On the other hand, most of these buildings are located in the regions of high seismicity. The behavior of tall buildings under seismic effects is crucial since the contribution of higher mode effects is significant on their dynamic behavior. Seismic response of tall buildings under the effect of seismic loading is one of the most sophisticated problems in earthquake engineering. High strength materials and innovative structural systems are generally employed to resist the unique challenges introduced by these structures in the regions of high seismicity. In this study, the behavior of tall buildings under seismic loading is summarized first by utilizing the performance based seismic design (PBSD) approach since current prescriptive seismic codes are too restrictive and inadequate to understand the anticipated behavior of tall buildings and pursue a reasonable design. Considering all these facts, several institutions and building officials have recently proposed and published alternative consensus guidelines, which are based on performance based design concepts. In this study, all of these issues are addressed. PBSD is commonly conducted by performing nonlinear dynamic analysis (NDA) for tall buildings. PBSD approach is quite sophisticated and a time consuming process, from creating nonlinear modelling to the interpretation of results. However, there are also variety of uncertainties from modelling of the component to the selection of ground motions, and to the definition of performance target levels. This study especially focusses on nonlinear modeling of reinforced concrete shear walls. Finally, a reinforced concrete unsymmetrical-plan tall building with 34 stories is designed in Istanbul according to the Turkish Seismic Code. For both service and maximum earthquake levels, nonlinear time history analysis is employed by using a suite of ground motions for checking the results in compliance with the determined target performance levels. The results have indicated that satisfactory seismic performance can be obtained through the use of performance based seismic design procedures.

Performance Based Seismic Evaluation of a 62 Story RC Tower in Istanbul Budak, Erhan; Sucuoğlu, Haluk (2018-06-18) A 62-story tall reinforced concrete office building with a free-standing height of 250 m has been designed in Istanbul in accordance with the new Turkish Earthquake Code (TEC, 2017). According to TEC 2017, buildings taller than 70 m and located in the first and second seismic zones are classified as tall buildings and these building shall be designed to meet the special rules based on performance-based seismic design approach. The tall building in Istanbul, having a parallelogram shaped floor plan and reinf...
Planning considerations of tall buildings : service core configuration and typologies Keskin, Zeynep; Günel, Mehmet Halis; Department of Building Science in Architecture (2012) In general, tall buildings, some of which are termed as “skyscrapers”, are among the typical and almost unavoidable features of the metropolitan cities. There is a competititive race of constructing higher and higher buildings since the birth of the infamous Home Insurance Building in Chicago which is still considered to be the pioneer of the modern tall buildings. Recently, an efficient service core design is strongly needed and inquired with the increase in height and capacity of tall buildings. Such need...
Seismic behavior assessment of low-rise reinforced concrete structural walls using quasi-static reversed cyclic loading protocol Ezzatfar, Pourang; Canbay, Erdem; Özcebe, Güney; Department of Civil Engineering (2016) The reinforced concrete shear walls of low- to mid-rise residential buildings, having height to length ratio ranging from 1 to 3, are more of a concern in research studies in recent years. Since the failure mode of these walls depends on the interaction between shear and flexural action, predicting the failure mode of this type of shear walls is not straight forward. While seismic behavior of highrise walls (i.e. aspect ratio greater than about 3) is almost known and theoretical assumptions matches well wit...
Seismic behavior of reinforced autoclaved aerated concrete wall panels TAGHIPOUR, ARMIN; Canbay, Erdem; Binici, Barış; ALDEMİR, ALPER; Uzgan, Ugur; ERYURTLU, ZAFER (2018-09-01) Vertical reinforced autoclaved aerated concrete (AAC) panel systems are among attractive alternatives for low‐rise buildings. The popularity of AAC panels in building construction is increasing due to their unique material properties, such as being light weight, good insulator, fire resistant combined with having high speed of erection and ease of quality control. However, past experimental evidence on the seismic response of reinforced vertical panels is rather limited with few tests on multi‐panel specime...
Performance based seismic design of reinforced concrete tall buildings Budak, Erhan; Sucuoğlu, Haluk; Department of Civil Engineering (2015) Cities, their economies and populations are steadily increasing all over the world. In parallel, the land prices in those cities are rising enormously, hence the need for new living spaces has been arisen. These results bring some obligations and new perspectives for those cities in order to address their needs. In addition, improvements and developments in technological equipment, material science and analyses methods have opened great opportunities to construct new life areas by rising the vertical direct...
